Collarette · 2–4"LavenderW. McClaren (Alpen Gardens) (2004)United States
Alpen Diamond is a collarette dahlia that opens 2–4" blooms in lavender. A lavender-pink ring of petals opens around a bright white collar that pales as the bloom ages. The color does a quiet shift from day one to day four that photographers notice before florists do. It was bred in United States by W. McClaren (Alpen Gardens) in 2004.

- Space roughly 2–3 ft apart
- Staking
